Xu Fei opened the virtual machine and landed in Wumeng's store. Xu Fei didn't exchange the resources in the Wumeng before, because he didn't have money, although "Gui" said that he could use her points, but Xu Fei didn't like to owe others much, so he didn't use "Gui" points all the time, even if the other party was his nominal teacher.

As for how to think about exchanging it now, the reason is very simple, because Xu Fei has money. This will involve the popularization of new energy. Since Xu Fei's secret pattern was handed in, the state began to open companies, factories, and manufacturing equipment in various cities. It took about a month from the establishment of the company to the manufacturing equipment, and the remaining three months were used for manufacturing and sales.

Within three months, new energy has begun to be widely popularized, and both civilian and military have begun to replace many general solar products. If it's just an energy absorption secret pattern, it will definitely not be popularized so quickly, the key is that Xu Fei's energy conversion secret pattern can purify the violent energy, and the technology of energy conversion into electrical energy has long been mature, so Xu Fei's new energy is popularized so quickly.

At present, some equipment that requires high-purity and high-energy energy levels cannot be replaced, such as some aircraft, and the defense system of some facilities, which require extremely pure energy, but can be used as backup energy.

Now that consideration has been given to adding this energy conversion secret to the defenses of the major cities. As long as this secret pattern is added to the defense system of major cities, then some energy will not be so violent, and ordinary people can also absorb it, enhancing physical fitness and longevity. Now this matter has also been included in the scope of the assessment.

Some scientists who have studied the body thoroughly say that this idea is not optimistic, because it is not only adults but also children and babies living in cities. Children and babies are not fully developed, and if they receive too many energy particles, they will cause irreversible damage to their bodies, so the city's defense system can only use a first-level secret pattern at most. But scientists also said that in some academies, martial arts halls, and dojos, it is possible to use the secret pattern of level 3 or above to transform energy and help martial artists practice.

Some martial arts halls, dojos, and the military have a government background, so it will be cheaper to purchase.

The evaluation is an evaluation, but the government still came up with 10 indicators as the first batch of pilots, so that major cities and colleges can compete, so it is not lively.

More importantly, in the past few days, many foreign heads of state have brought many businessmen, warriors, and people with extraordinary abilities to China for friendly visits. Needless to say, I also know that we are talking about new energy in the name of a friendly visit. Since the patent application of new energy to the advent of new energy products, spies from many countries have poured into China to get information on new energy. Not surprisingly, nothing was found.

After the advent of new energy products, some other countries also got the products, and dismantled them, took out the secret pattern core, and prepared to reverse engineer, but without exception they all failed and could not be imitated, so the heads of state of many countries came to visit and wanted to seek cooperation and obtain new energy.

Three months is not long, and it is not short. At least not the students, who are rarely concerned with these big issues in closed schools. But Xu Fei has been paying attention, and in the past three months, which is also the first quarter of the company, Xu Fei has gained amazing wealth.

The shop inside the Martial Alliance is very interesting, with many sections, such as spells, potions, materials, weapons, armor, sundries, and so on.

Techniques are some swordsmanship, knife techniques, hammer techniques, fist techniques and other martial arts classics, and potions are medicines that can repair or enhance physical wounds, as well as poisons, antidotes and so on. In the material, Xu Fei saw many fierce beast body parts, bones, blood, beast spars, etc., this beast spar is a unique material of green-level fierce beasts, which has extremely high purity xenogeneous energy, which cannot be absorbed and utilized, so it looks like a chicken rib.

A long time ago, human warriors discovered that these beast crystals contained extremely pure and extremely high energy levels, but this energy was extremely condensed and could not be used at all, and over time, no one was researching.

The weapons and armor are made of materials on the body of some fierce beasts, the conductivity of the yuan force is very good, the armor is made of the fur of the fierce beast, and the texture is very good, especially the armor, the leather armor made by those yellow-level or even green-level fierce beasts cannot be broken by the martial artists of the Yuan Jiuzhong.

Xu Fei chose ten life recovery elixirs, two cell activation elixirs, and three mental stimulation elixirs in the potion section. The recovery ability of the life recovery potion is extremely powerful, it is extracted from the body of some Kun beasts, and the Kun beasts are much more powerful than other beasts of the same level, the reason is in their vitality, after taking it, they can recover from injuries in a short time, and can also be used as medical treatment, treatment of disabilities, regeneration of broken fingers, etc.

Cell activation agents are agents that increase cell activity in a short period of time, and can improve the user's endurance, stamina, and recovery in a short period of time. There are some side effects. The user will feel collapsed after the effects of the drug have passed.

As for the mental stimulation elixir, it is also a medicine that increases sensitivity in a short period of time, and it is the product of the struggle between the martial arts league and the naturalistic faction, because there are many martial artists who attack the natural faction, so the mental stimulation elixir is used to improve perception and strengthen the spirit. The side effects are not significant.

In addition to these three elixirs, Xu Fei also bought two beast crystals, and he had some faint thoughts about beast crystals in his heart.

After his purchase was completed, Xu Fei bought ten more life recovery elixirs, three gene-strengthening elixirs, three yuan myeloid liquids, and then took out two animal bones to make rings with broken diamonds and ordinary appearance.

The name of the gene enhancement medicine is good, but in fact, it is just some strengthening medicine, which can strengthen the physical fitness of ordinary people to the level of cohesion between the double and triple martial artists, but the yuan medullary fluid is not simple. This element marrow fluid is the essence of life extracted from the bone marrow of the fierce beast, which can repair the body's dark wounds, defects, wash the marrow and remove hair, and is an enhanced version of the gene repair solution. These three copies were purchased only by Xu Fei using the authority of "癸".

As for the ring, it is engraved with a secret pattern to improve qualifications.

These are all for his family, and Xu Fei now knows a little about his parents' previous affairs. In fact, his father didn't want to become a martial artist, but because he practiced wrong in his early years, which caused his body to be unable to continue cultivating.

Xu Fei's mother was originally the third daughter of the Cai family in Rongcheng, who showed a talent for martial arts since she was a child, and originally planned to learn martial arts, but she was expelled from the Cai family because she was framed, and the person who framed her used her influence to make Cai Qin unable to enter the martial arts school, and finally went to an ordinary university.

Xu Fei's father wanted to learn martial arts because he had seen the "Three-Eyed Blue Stone Dragon" with his own eyes when he was a child, but he was too eager for quick success and damaged the foundation, and the cost of drugs that could repair the defects was too great for Xu Fang to bear, so he could only give up the path of martial arts.

What Xu Fei has to do now is to re-pave the road, as for how to choose, it depends on them.

A day later, Xu Fei received the purchased goods.

When I opened the box, there were two rows of potion bottles that were much smaller than my little thumb, and the life recovery potion was green, the cell activation potion was red, and the mental stimulation potion was blue.

In addition, there are two spars, one large and one small, showing a regular prismatic structure, boxy, and the appearance looks extremely perfect, the large one is dark brown, and the small one is light brown.

For this beast crystal, Xu Fei had already guessed in his heart, he knew that this beast crystal was something that only existed in the body of a green-level fierce beast, and the energy contained in it was needless to say that it must be the energy of the biological force field. In fact, the high-level leaders of the Martial Alliance all understood that this was indeed the energy of the biological force field, but the energy in it could not be applied, and even the most advanced tools could not cut this beast crystal.

At that time, human beings thought of many ways to study this beast crystal, but all of them failed. Even "Zhou", one of the four titled powerhouses, attacked the beast crystal and wanted to see the energy changes in it.

At first, the attack of the "Zeus" had no effect, but as the attack intensity of the "Zeus" increased, the originally extremely stable energy in the beast crystal actually burned, and finally exploded. The power is comparable to that of a nuclear bomb with a yield of 200,000, except that there is no nuclear radiation.

Later, the research on the beast crystal was stopped, because the energy in it could not be used at all, and although the energy in it was powerful, the utilization rate was not as good as that of the sylvestite.

Others had no way to use it, but Xu Fei thought that if he could get out the energy of the biological force field in it through the secret pattern and absorb it for himself, then it would be much stronger than refining the Xuanjing Stone. The energy in the Xuanjing Stone is all energy particles, and it can only be turned into true elements after refining, but the energy in this beast crystal is all true elements, and it can be directly absorbed and refined.

Xu Fei picked up a light brown beast crystal that was much smaller, and his spiritual sense expanded and penetrated inside. Suddenly, his face changed, revealing a strange look.

"Huh? What's going on? ”

Because when Xu Fei's spiritual sense penetrated into it, he felt blocked, and it seemed that this beast crystal had the effect of isolating spiritual sense and spiritual power.

"It's a lot of resistance, but it's hard for me."

If Xu Fei hadn't used his spiritual power alone before condensing into spiritual consciousness, it would definitely be impossible to invade the interior of this beast crystal, unless his spiritual power was increasing several times. But now Xu Fei's condensation spiritual sense is essentially much higher than his spiritual power, and there is no need to directly invade at all, so Xu Fei's spiritual sense has changed from the original violent invasion type to the infiltration type.

The spiritual sense changed invisibly, slowly penetrating inward, and the spar that originally had the power of blocking could not feel the powerful spiritual invasion and became calm, and gradually Xu Fei's spiritual sense began to penetrate into the spar silently.

After the spiritual sense gradually "squeezed" into the beast crystal, Xu Fei's eyes suddenly widened.

I saw that the inside of this beast crystal was a chaotic world, although it was only the size of a child's fist from the outside, but the inside was very vast, making people feel very funny, as if they had suddenly shrunk ten million times. This feeling almost made Xu Fei think that he had returned to the space of consciousness.

However, in an instant, Xu Fei calmed these thoughts, and looked into the distance, only to see a chaotic flow of air currents rhythmically, these air currents passed through Xu Fei's spiritual sense, and seemed to be operating according to a specific route.

"These are all real elements."

Xu Fei was a little surprised, these true elements showed a chaotic color, they were all the most original and purest true elements, under the spiritual sense, the purity of these true elements was much purer than his true yuan, and Xu Fei felt that these true elements seemed to have their own consciousness.

True Yuan is the product of the mixture of spirit and Yuan force, and consciousness is also reasonable, which is the spiritual breath that belongs to the individual.

But now that you look at it, it's a little scary. Because Xu Fei once experimented and output a little true element, if the connection is disconnected, the spiritual aura in the true element will become blank, and the unique attributes of the true element will also disappear, becoming an ownerless true element.

But if you look at it now, the true element in it still has a spiritual breath, and it has not become an ownerless true element, so this means that the owner of this beast crystal is dead in a sense.

"How is this possible?"

These beast crystals were all taken from the corpses of those green-level fierce beasts, and from a practical point of view, they should be dead. But the breath of this true yuan was telling Xu Fei that the owner of this beast crystal was not dead.

After a little contemplation, Xu Fei immediately reacted: "It must be related to this beast crystal." ”

"This beast crystal is something that only exists in the body of a green-level fierce beast, why is it only available in the green-level beast. Because the green-level fierce beast will have the true element, and the true element is the product of the combination of spirit and spirit to me, so what about the fierce beast? How do they produce true elements? ”

"Could it be that when they evolved, their bodies underwent a metamorphosis, and they also produced life energy, and then, according to the instinctive trend, they merged the essence and spirit and life energy into one, and produced the true element? So is this beast crystal the product of the fusion of essence and spirit and life energy? ”

Xu Fei felt that even if his guess was not all right, then it was seven or eight times out of ten. But if your guess is correct, then this represents a terrible fact.

That is, it is very likely that the fierce beasts above the green level that humans killed in the past are not really dead.

Xu Fei decided to take a good look at the inner space of this beast crystal.

The spiritual sense drifted with the waves, gradually coming to the convergence place of this true element flow, which was also the center of the entire beast crystal space. In this very center, Xu Fei found an illusory beast lying on his back, really swallowing the true yuan around him. This illusory beast resembles a rat with an extremely long tail that is about three meters tall.

Seeing this illusory mouse, Xu Fei remembered the owner of this beast crystal, the gopher-splitting.

"I didn't expect it to be really dead."

Xu Fei doesn't have any good feelings for these fierce beasts, although this spirit body is the spirit body of a green-level fierce beast, but it is not so powerful, but since it is the owner of this beast crystal, it can operate the true element inside it, and the true yuan has the power to eliminate the spirit, so they are almost invincible within this beast crystal.

Unless an external force breaks through this beast crystal, they can almost live until the true element in this beast crystal is completely consumed.

Looking at the fierce beast spirit body that was swallowing the true element, Xu Fei sneered, in the distance, there may only be a way to escape, but in the near distance, Xu Fei is not afraid of it counterattacking, because the distance is too close, and the other party can't use the energy in this beast crystal.

As a result, Xu Fei's spiritual sense changed, turning into a spiritual sense membrane, enveloping the spiritual body of this fierce beast in an instant, cutting off its spiritual connection with the true element in the beast crystal space.

That's right, Xu Fei just wants to swallow it, just like it swallowed humans a long time ago.
